Use Kerberos Hub with your own style guide and marketing branding.

Kerberos Hub can be styled towards your company marketing branding and/or preferred style guides. By injecting a custom CSS file, and overriding our icon library, you can make Kerberos Hub feel like it’s your own product; and we do not have any problem with that.

We believe that a consistent and streamlined company branding is important when using 3rd party applications in your companies ecosystem.

Next to styling Kerberos Hub yourself, we can also rebrand the application for your needs as part of the Kerberos Enterprise Suite license. In the end nothing stops you to perform the layout changes yourself, whenever you want.

By injecting a CSS file into the Kerberos Hub Front-end container, you can choose your own colors.

Overriding the Kerberos Hub styling

The recommended approach to add your custom styling is to inject a custom stylesheet file .css in the Kerberos Hub Front-end container. Let’s start by creating a .css file, and include all the relevant CSS elements which you would like to modify. This could look like this.

.app .sidebar.closed {
  background: red !important;
}

To know which element you need to style, we advice to use the inspect elements tool of your Chrome/Safari/Firefox browser developer tools.

Once you are happy with your styling, you can proceed with the injection in the front-end container.

Injection is done through the concept of Persistent Volumes (PV). A PV is mapped in a front-end container, and is overriding the local directory of the front-end container with your changes made in the PV. If you are not familiar with a PV, you might need to learn about it first.

Once you created a PV and uploaded your stylesheet, you should create a Persistent Volume Claim (PVC), so you can share it with the Kerberos Hub front-end container.

To share the PVC, you need to make a few changes in the Kerberos Hub Helm chart values.yaml. Uncomment the volumeMounts and volumes properties. Change the PVC accordingly and keep the mountPath unchanged.

If all set, commit your changes by doing an helm install or helm upgrade.

Similar to overriding the Kerberos Hub styling you can inject your own company logo as well. This logo will be used on the login page and sidebar once signed in. Make sure to name your company logo as following, logo-sidebar.svg.

To inject your logo, upload it into the same PV as you used for the custom styling.

Add custom icons

If you do not like the icons we are using, you can also modify those by injecting your own SVG icon library. An example of the icon library can be found here: icon.js.

All icons are sorted in alphabetic order, and each icon has a generic naming convention and relevant SVG element.

Make sure you are using SVG icons, we do not support other formats at the moment of writing.

Add custom favicons

Favicons are injected into the container just like the custom stylesheet, logo and icons. The only difference is that they are not stored in the custom directory, but are stored in the favicons directory. An example of the favicons content can be found here.

To make this work an additional volumeMount has to be created and relevant PVC. Once you’ve done that you will see your own favicons appear.
